What does a brain do?
The brain is the control centre of the central nervous system, responsible for perception, attention, memory, emotion and action.
Well we need brains to think
The brain is the convoluted organ within your cranium (skull). It is the major part of the central nervous system, controlling the functions of the body. It is also the seat o…f cognitive intelligence. The human brain consists of four major parts: cerebrum, cerebellum, brain stem, and diencephalon. (the dienchephalon may also be grouped within the brain stem)
There is about 160,000,000,000 cells in human brain. Half of the number are neurons, which are rensponsible for all the "thinking" functions. The other half are "glial cells",… which help neurons with their activity.
Your brain is the organ that enables you to manipulate and navigate the world around you.
In one sense, since humans are animals, your brain does not differ from the brina of an animal. human brains, and those of the other great apes, do differ from those of other… animals in size relative to body size. In addition, human brains have structured that some other animals, reptiles, for example, lack.
Usually rack one's brain. However, according to Oxford dictionary online, it's either: PHRASES rack (or wrack) one's brains make a great mental effort. - ORIGIN from Dutch …rec, Low German rek 'horizontal bar or shelf', probably from recken 'to stretch, reach'. (also suggested is that the Dutch rec (framework) leads to the Middle English rakke)
Let's consider an analogy. The Human body and the computer: The brain can be compared to the CPU of a computer. The Skeletal muscular system would then be the equivalent of …the key board. The Skeletal muscular system is the one and only part of the human body that we can feel and control. In a computer, does the key board controls the CPU or the CPU controls the key board? For the manufacturer, one controls the other. He has to improve both so that the interaction between the two becomes easier and more reliable. However, according to the user it is the key board that controls the CPU. In fact, he need not even have to know that the computer has a CPU. The brain can't be improved. We can only make the best use of what we have got. What is 'I' anatomically? What is the 'You' we are talking about? Lets consider its first person equivalent, 'I'. What is this 'I' anatomically? All the skeletal muscles of the body can contract and relax isometrically as a single unit called Unified Skeletal Muscle, popularly known as the mind. This can contract voluntarily (under our control) or involuntarily (On its own). As default, the voluntary part is trapped between two layers of involuntary parts. This voluntary part of the Unified Skeletal Muscle or Mind is what we call 'I'. The involuntary part is what we call Self. What controls the brain? Under normal conditions it is the 'I' that controls our entire life through the brain, the brain playing a very passive role. In fact, we need not even have to know that we have a brain to use the brain.
The hypothalamus is sometimes called "the brain of the brain". It is the hub for many automatic and homeostatic systems, including the circulatory system, metabolic processes,… and sensory inputs.
It depends on the area of the brain affected -- here's a link to a good website that gives you specific problems caused by damage to specific parts of the brain. If a man has… a brain damaged in an accident , he could well be in a coma or even end up as a vegetable. MY BRAIN DAMAGE CAUSES ME TO SHAKE UNCONTROLABLY MY ENTIRE BODY I AM SLOW AT TALKING AND STUFF LIKE THAT BUT I AM VERY SMART IT JUST TAKES ME LONGER TO SAY IT it can be like a computer virus: works fine one minute, then a virus comes in and there can be any type of problem that the virus comes with
Nothing. Commonly it's a cold headache. Cold Stimulus Headache. Although we use the term pain for the brain, there is no such thing. The vessels and nerves around the brai…n are what is causing the "pain" you feel. Brain freeze is a headache most commonly associated with the quick consumption of cold substances, such as ice cream. When the cold substance comes into contact with your palate or the roof of your mouth and sinus cavities it causes the blood vessels to vasoconstrict or get smaller. As the palate warms the blood vessels dilate. This rapid constriction and dilation is detected by pain receptors that travel to the brain via the trigaminal nerve, which also serves as one of the major nerves for the facial area. Because the pain signal travels with the signals coming from the face, the brain thinks it is feeling pain in the face that isn't really there, this is called referred pain.
The brain stem connects the brain to the spinal cord, so that the brain can send messages through the cord to the rest of the body. The functioning of the body is severely com…promised if the spinal cord connections are severed.
If you didn't have a brain, you really couldn't do anything pretty much. Example: You wouldn't be able to walk, because you would forget how to walk. Why we have a brain? …We have a brain so we can think, ( or walk. :-} ) If you didn't have a brain you wouldn't be able to ask this question. Actually walking is controlled almost entirely by nerve paths in the spine, the brain is not involved except to select where we are walking to (part of thinking).
It is weird but the right side of your brain is connected to the left side. The brain stem deals with very very important functions that keep us alive.
The brain stem, otherwise known as the medulla, controls all your involuntary actions, such as heartbeat and digestion.
The parts of the brain are the cerebrum, cerebellum and the brain stem. The cerebrum makes up 90% of the brain and controls speech, memory, thoughts and all conscious actions.… The cerebellum controls balance and co-ordinates complex muscle movements. The brain stem controls all unconscious thoughts such as ; heat rate and breathing
